Hi, I'm redoing my bathroom and have already pulled the cast iron tub and tile out. Next I'm gonna pull up the tile floor. I'm adding ship lap to the 4 walls (floor to ceiling) and trying to figure out how many bundles to order. The bathroom is 5' * 8' with 7 1/2' height. 1 window and 1 door. Each board is 1" * 8" * 6'.

Additionally, what are you doing for walls around replacement tub? How are you trimming the window and door? Baseboard? Too many questions for me to be totally comfortable with my off the cuff estimate of ten bundles.

Ross, we are installing them horizonally. Unfortunately, the style we liked only comes in 6'. The others we looked at where 8' which obviously would be much better as now we have to have a cut on the 2 8' walls.

I was at someone's house recently and they didn't trim the baseboard. Just the ship lap over the new tile. I may go with that.

Assuming window and door in the 5' walls, you should be good with ten or eleven bundles. You should do the eight foot walls first as you will have a lot of cuts to stagger your joints so they at not on top of one another. Any left over cut offs from this should be used to fill around window and door which will be short runs. See if they have a quarter round, or other moulding in same finish for corners if you are not confident of making consistent finish cuts. This will also cover any out of plumb wall framing.

What was wall tile on? The reason I ask is you need to figure out the projection of the shiplap to the window and door jamb. If the shiplap is proud, or out further than the jambs, you need to make up jamb extensions. If it is shy, you need to pad out the studs. Take a four foot level and place across interior of window and door. Measure distance to studs. That number minus thickness of shiplap is what you need to figure it out. Shiplap is usually 3/4.

The ideal numbers would be 3/4 (just install shiplap to studs), or 1 1/4 you would skin the walls with 1/2 inch plywood which would alleviate the need of using just studs for fastening
